The Invention of Battlezone – IEEE Spectrum

King Camp Gillette decreased the worth of the razors, and the demand for razor blades elevated. The historical past of IT comprises quite a few examples of this phenomenon, too.

I contend, furthermore, that there are nonetheless different regularities within the subject of computing that is also formulated in a vogue much like that of Moore’s and Metcalfe’s relationships. I wish to suggest 4 such legal guidelines.

Regulation 1. Xmas’s Regulation of Complementarity

I named this legislation after George Udny Xmas (1912), who was the statistician who proposed the seminal equation for explaining the connection between two attributes. I formulate this legislation as follows:

If two attributes or merchandise are enhances, the worth/demand of one of many enhances can be inversely associated to the worth of the opposite complement.

In different phrases, if the worth of 1 complement is decreased, the demand for the opposite will enhance. There are a number of historic examples of this legislation. One of many well-known ones is the advertising and marketing of razor blades. The legendary King Camp Gillette gained market domination by making use of this rule. He decreased the worth of the razors, and the demand for razor blades elevated. The historical past of IT comprises quite a few examples of this phenomenon, too.

The case of Atari 2600 is one notable instance. Atari video video games consisted of the console system {hardware} and the read-only reminiscence cartridges that contained a recreation’s software program. When the product was launched, Atari Inc. marketed three merchandise, particularly the Atari Video Laptop System (VCS) {hardware} and the 2 video games that it had created, the arcade shooter recreation Jet Fighter and Tank, a heavy-artillery fight title involving, not surprisingly, tanks.

Crucially, Atari engineers determined that they might use a microchip for the VCS as a substitute of a customized chip. In addition they made positive that any programmer hoping to create a brand new recreation for the VCS would have the ability to entry and use all of the interior workings of the system’s {hardware}. And that was precisely what occurred. In different phrases, the designers decreased the boundaries and the fee essential for different gamers to develop VCS recreation cartridges. Greater than 200 such video games have since been developed for the VCS—serving to to spawn the sprawling US $170 billion international online game business immediately.

An identical legislation of complementarity exists with laptop printers. The extra inexpensive the worth of a printer is stored, the upper the demand for that printer’s ink cartridges. Managing complementary parts properly was additionally essential to Apple’s successful the MP3 participant wars of the early 2000s, with its now-iconic iPod.

From a strategic standpoint, know-how corporations in the end must know which complementary component of their product to promote at a low value—and which counterpoint to promote at a better value. And, because the economist Bharat Anand factors out in his celebrated 2016 guide The Content material Lure, proprietary enhances are typically extra worthwhile than nonproprietary ones.

Regulation 2. Hoff’s Regulation of Scalability

This legislation is known as after Marcian Edward (Ted) Hoff Jr.—the engineer who satisfied the CEO of Intel to use the legislation of scalability to the design and growth of processors. Actually, the phenomenon of scalability was well-known within the car business earlier than it made a big influence on the computing business. Henry Ford was a notable instance of the appliance of this scalability legislation. Henry Ford’s firm was maybe the primary firm to use this legislation on a grand scale. Ford produced the Mannequin T, which was the primary mass-produced automobile. On the core of Henry Ford’s achievement was the design of an car that was made for mass manufacturing. Ford’s engineers broke down the meeting technique of the Mannequin T into 84 discrete steps. The corporate standardized all of the duties and assigned every employee to do only one process, thus standardizing the work every employee carried out as properly. Ford additional constructed machines that would stamp out elements routinely. Along with Ford’s modern growth of the primary shifting meeting line, this manufacturing system lower the time to construct a automobile from 12 hours to about 1.5 hours. The Mannequin T might be the paradigmatic instance of how standardization permits designing processes for scalability.

Till the early Sixties, every IBM system had its personal distinct working system, processor, peripherals, and software software program. After the acquisition of a brand new IBM laptop, prospects needed to rewrite all their current code.

Intel additionally mastered the legislation of scalability early in its historical past. In 1969, Busicom, a Japanese firm, approached Intel about constructing customized chips to be used in its programmable computer systems. Gordon Moore was not concerned about a customized chip as a result of he knew that it could not be scalable. It was the search to create a scalable product that led Intel’s Ted Hoff to partition the chip right into a general-purpose logic processor chip and a separate read-only reminiscence (ROM) chip that saved an software program. As Albert Yu reveals in his historical past of Intel, Creating the Digital Future, the fledgling semiconductor firm’s general-purpose processor, the 4004, was scalable and just about bequeathed the world the {hardware} structure of the fashionable laptop. And it was Hoff who redesigned the 4004 to scale. Hoff’s Regulation of Scalability may thus be described as follows:

The potential for scalability of a know-how product is inversely proportional to its diploma of customization and immediately proportional to its diploma of standardization.

In sum, the legislation predicts {that a} know-how part or course of that has a excessive diploma of customization and/or a decrease diploma of standardization can be a poor candidate for scaling.

Regulation 3. Evans’s Regulation of Modularity

This legislation derives its identify from Bob Overton Evans. He was the engineer who within the early Sixties persuaded IBM’s chairman, Thomas J. Watson Jr., to discontinue IBM’s know-how design method, which had produced a hodgepodge of incompatible computer systems. Evans advocated that IBM ought to as a substitute embark on the event of a household of modular computer systems that will share peripheries, directions, and customary interfaces. IBM’s first product household beneath this new design rubric was known as System/360.

Previous to this period, IBM and different mainframe laptop producers produced techniques that had been distinctive. Every system had its personal distinct working system, processor, peripherals, and software software program. After the acquisition of a brand new IBM laptop, prospects needed to rewrite all their current code. Evans satisfied CEO Watson {that a} line of computer systems needs to be designed to share lots of the identical directions and interfaces.

If a paper is copied 4 occasions, one can now share the useful resource with 5 individuals. However digitize the doc and the value-creation alternatives are multiplicative moderately than additive.

This new method of modular design meant that IBM’s engineers developed a standard structure (the specification of which features and modules can be a part of the system), frequent interfaces (an outline of how the modules will work together, match collectively, join, and talk), and customary requirements (a definition of shared guidelines and strategies that will be used to realize frequent features and duties). This daring transfer on Large Blue’s half created a brand new household of computer systems that revolutionized the pc business. Clients may now shield their investments as a result of the directions, software program, and peripheries had been reusable and suitable inside every laptop household.

Evans’s Regulation might be formulated as follows:

The inflexibilities, incompatibilities, and rigidities of advanced and/or monolithically structured applied sciences might be simplified by the modularization of the know-how buildings (and processes).

This legislation predicts that the appliance of modularization will cut back incompatibilities and complexities.

One additional instance of Evans’s Regulation might be seen within the software program growth business, because it has shifted from the “waterfall” to the agile software program growth methodology. The previous is a linear and sequential mannequin stipulating that every venture section can start solely the earlier section has ended. (The identify comes from the truth that water flows in just one course down a waterfall.) In contrast, the agile growth method applies the legislation of modularization to software program design and the software program growth course of. Agile software program developments are typically extra versatile, extra responsive, and quicker.

In different phrases, modularization of software program tasks and the event course of makes such endeavors extra environment friendly. As outlined in a useful 2016 Harvard Enterprise Assessment article, the preconditions for an agile methodology are as follows: The issue to be solved is advanced; the options are initially unknown, with product necessities evolving; the work might be modularized; and shut collaboration with finish customers is possible.

Regulation 4. The Regulation of Digitiplication

The idea of digitiplication is derived from two ideas: digitalization and multiplication. The legislation stems from my very own examine and observations of what occurs when a useful resource is digitized or a course of is digitalized.

The legislation of digitiplication stipulates that at any time when a useful resource or course of is digitalized, its potential worth grows in a multiplicative method.

For instance, if a paper is copied 4 occasions, one can now share the useful resource with 5 individuals. However digitize the doc and the value-creation alternatives are multiplicative moderately than additive.

Think about the instance of a retail retailer. The shop’s gross sales reps, tasked with promoting bodily merchandise to particular person individuals, are in a position to service just one buyer at a time. Nevertheless, if the identical retail surroundings is positioned on-line, many shoppers can view the shop’s services and products. Digital textual content may simply be reworked into an audio format, offering a unique form of worth to prospects. Search performance throughout the retailer’s stock after all provides one other layer of worth to the client. The shop’s managers may monitor what number of prospects are viewing the shop’s web site’s pages and for the way lengthy. All of those enhancements to the client’s (and retailer’s) expertise present completely different sorts of worth. As might be seen by these examples, the digitalization of a useful resource, asset, or course of creates multiplicative moderately than additive worth.

As an additional instance, Amazon founder Jeff Bezos first started digitizing knowledge about books as a technique to facilitate extra and higher guide gross sales on-line. Bezos rapidly reworked Amazon right into a digitiplication engine by turning into a data-centric e-commerce firm. The corporate now advantages from the multiplicative results of digitalized processes and digitized info. Amazon’s search, choice, and buy features additionally enable the corporate to document and produce knowledge that may be leveraged to foretell what the client desires to purchase—and thus choose which merchandise it ought to present to prospects. The digitization of buyer suggestions, vendor rankings, and vendor suggestions creates its personal dimension of multiplicative worth.


These 4 legal guidelines might be helpful for engineers and designers to pose questions as they start to develop a product. For instance: Do buyer necessities lend themselves to a product design that might be scaled (or mass-produced)? Would possibly the practical necessities they’re working with be glad via the event of a modular product design? Might Xmas’s Regulation of Complementarity present cues towards mass manufacturing or modular design alternate options? Might product enhances be developed in-house or outsourced? Software program engineers may also be led towards productive questions on how knowledge might be digitized, or how particular processes might be digitalized to leverage the legislation of digitiplication.

The fields of IT and electrical engineering and laptop science (EECS) have grow to be important disciplines of the digital age. To move alongside probably the most succinct and related formulations of gathered information to this point to the following technology, it is incumbent on teachers and thought leaders in these important technical fields to translate classes discovered into extra formalized units of theorems and legal guidelines. Such formulations would, I hope, allow present and future generations of IT and EECS professionals to develop probably the most helpful, related, impactful, and certainly typically even disruptive applied sciences. I hope that the proposed 4 legal guidelines on this article may assist to set off a bigger dialogue in regards to the want for and relevance of recent legal guidelines for our disciplines.
